3 Claims.

The invention relates to heating systems for railway cars and other vehicles in which the radiators and connecting pipe lines are mounted and concealed within the plane of the wall accommodating them.

Heretofore, the heating equipment for railway cars has involved the use of apparatus disposed within the space intended for the use of passengers, and because of the bulk of such equipment, the occupants of the car have been deprived of suflicient room for their baggage and comfortable disposal of their persons. A further disadvantage resulted. from the obstruction to complete door movement and the necessity for cutting away partition and furniture parts to properly fit them to the sidewall and projecting pipe housings.

The foregoing and other evils have been overcome by the invention which has for its principal object the concealment of heating coils and pipes within the walls of the car, to the end that the space normally occupied by the passengers shall be free of allv protruding heating apparatus. A further object is to position the heating apparatus in wall recesses and intermediate communicating passages and so dispose the coils and connecting pipes that the surfaces thereof will be exposed to the air o-f the car interior, and the installation rendered accessible for inspection and repair.

The foregoing and other objects are attained by the construction illustrated in the accompanying drawings, in which Figure l is an inside elevational View of a portion of a car wall having the heating system concealed behind grille wainscoting;

Figure 2 is a horizontal sectional view taken on line 2 2, of Figure 3, showing a radiator installed in the wall between two posts of the car framing;

Figure 3 is a vertical sectional view taken on line 3 3, of Figure 1, showing the mounting of the radiator units and connecting pipe lines, with associated grille wainscoting and framing parts;

Figure 4 is a similar view through the posts separating the radiator units taken on line 4-4, of Figure 1, showing the communicating passages intermediate the radiator recesses;

Figure 5 is a similar view in fragmentary section showing a modified arrangement of the wire conduits to permit upward extension of the radiator recess.

55 In said drawings,

I0 represents a car wall (Cl. 10S-401) adapted to receivethe heating equipment in accordance with the invention, I I they windows, and I2 the radiator units of the system. The coils and connecting pipes are positioned between posts I3 of the car framing and between wainscoting grilles I4, I5, and I6, and adjacent girder side I'I, as best shown in Figures 2, 3, and 4.

Between the coils I2 and girder sides are deilector plates I8 extending preferably from post to post and from the floor I9 upwardly to a 10 point below the window sills 20. As indicated in the figures, the space between the girder sides and the several deflector plates I8 is lined with insulating material 2| designed to prevent the radiation of heat to the girder side and secured 15 to the girder and deector plates in any suitable manner.

As shown in Figure 1, the radiators I2 are disposed at spaced intervals along the wall I0 and separated by certain of the framing posts o I3 forming recesses 22 extending from the underframe longitudinals or floor strips 33 to the longitudinal deflector wall portions 23 for the accommodation of the radiator units. The longitudinal deilector wall portions 23 on dei-lector plates I8 function to direct the air heated by the radiators to the car interior and to connect adjacent posts I3 and wainscoting I4 as best shown in Figure 3.

In the present embodiment, the heated air in '30 the radiator recesses is prevented from entering wall areas beyond associated posts I3 by supplemental post elements 24 filling the space between the several posts I3 and respective wainscoting grilles I4 as shown in Figures 2, 3, and 4, and between the deflector wall portions 23 which are overhanging the radiators and the intermediate longitudinal framing strips 25 traversing recesses 22 and connecting the framing posts I3. The wainscoting grilles I4 are removably held 4o to the post elements 24 by battens 2B fastened by screws 2'I to post filler elements 24, by other screws 28 to longitudinal framing strip 25, and by screws 29 to contiguous longitudinal edges of deector Wall portions 23 bordering the margins 45 of the grille openings.

The wainscoting base grilles I5 are secured along their upper margins to the longitudinal framing strips 25 by the screws 28 fastening the lower edges of the relatively higher grilles I4, and at their lower edges to the oor I9 as shown in Figures 3 and 4. To prevent dirt and other matter from entering the radiator space 22 behind the grille I5, the grilles are preferably formed with an imperforate area 3| projecting above the 55 floor line to a height sufcient to effect that purpose. As indicated in Figure 3, the deector plates I8 extend to the floor line and terminate in lateral ange portions 32 designed to overlap and be supported upon adjacent iloor strips 33 of the underframe 34. Supported upon flanges 32 of the deflector plates are the strap brackets 35 adapted to carry the radiators I2 and secured to the deiiector plates by brazing or other means and to which the radiator coils may be attached by screw bolts 36 securing clamping plates 3l best shown in Figures 2 and 3. The brackets 35 are preferably formed to provide seat portions 38 for supporting the coils to relieve the screw bolts 36 of a portion of the Weight of the coil as shown in Figure 3.

It will be noted that the deflector plates I8 are extended upwardly beyond the overhanging wall portions 23 to provide wall areas 39 for securing the insulation 2| at that point, thence to the window sills and there secured by screws 40, or the like, as best shown in Figure 3. Thus arranged, space 4| is provided between posts I3 and adjacent wainscoting I4 for the accommodation of wire conduits 42, properly insulated from the underlying heated wall portion 23 of deflector plates I8, and removably attached to the posts by clamps 43 to avoid piercing the posts for the passage of the conduits.

In this embodiment, the coils I2 are supplied and drained respectively by pipe lines 44 and 45 communicating with automatic valve regulating devices beneath the car and not here involved. To avoid piercing the posts I3 between the coils, the pipe lines extend outside of the posts and through communicating passageways 46 between the radiator recesses 22. The supply line 44 is offset to connect with the coils in the plane of the posts while the drain line 45 retains a direct course to the regulating valve, both lines being positioned beneath the longitudinal framing strip defining the upper side of the passageways 46 and removably secured to the several posts I3 by clamps 47 heid by screws 48 as best shown in Figure 4.

Between the pipe lines 44 and 45 and the posts I3 in passageways 46, deflector plates 49 are adapted to close the space behind the pipe lines in the areas of wainscoting grilles I6 intermediate the base grilles I5, for the purpose of directing air drawn from the car interior to adjoining radiator recesses 22. By the action of the ascending air currents in said recesses the air in the passageways 45 is entrained by the air entering base grilles I5 to provide an air stream supplementing those developed in the recesses 22 by the emission and displacement of the air in the radiator Zone. As indicated in Figures 3 and 4, the relatively cool air adjacent the floor line of the car is drawn through the base grilles I5 and I6 and swept across the radiating field of the coils I2 and pipe lines 44 and 45.

The deflector plates 49 are provided with upper and lower attaching flanges 5D and 5| securing the plates to respectively adjacent framing and floor strips 25 and 33. Immediately above the openings in emission grilles I 4 the wainscoting is provided with hot air deiiecting strips 52 secured thereto by screws 53, or otherwise, to protect the wall areas above them from the ravages of the heat issuing from the grilles.

It may be desirable at times to increase the areas of heat emission grilles I4 by extending the radiator recesses upwardly to the window sills as shown in Figure 5. In that figure, the wire conduits |42 are in the plane of framing posts ||3, pierced to accommodate the conduits, to provide room for the upward extension of the radiator recesses. For this purpose the deector plates I I8 are oiset at |23, thence upwardly to the window sill |20, to provide wall surfaces for the attachment of insulation |2| for the protection of the conduits |42 from the heat of the radiators I I2.

As shown in Figure 5 the radiator supporting brackets are detachably secured at their respective upper ends to the window sill by screws 40. As in the case of the post fillers 24 of the preferred embodiment, fillers |24 are provided between Wainscoting grilles I|4 and adjacent posts I 3 to at once prevent dissemination of convected heat to areas beyond the radiator recesses |22 and provide abutments for the grilles secured to them by the battens |26.

It will be noted that there has been provided an arrangement in which the car structure and heating apparatus are co-ordinated to eliminate bulky groups of heating coils and their housings from the space between the walls of the car.

The full radiating value of the several coils in the present embodiment becomes available convectively by the constant circulation of air across the radiators drawn from and returned to the car interior. The arrangement makes possible a great saving resulting from the elimination of waste due to heat losses by conduction and faulty radiation incident to theuse of direct heating apparatus.

With the several upper Wainscoting grilles I4 removably secured to the wall, and the base grilles i5 and I6 consecutively arranged in the wall and also removably secured, a number of the coils I2 with their connecting supply and drain pipes 44 and 45 may be removed from and mounted within their respective Wall niches, as a unit.

What I claim is:

1. In a passenger car, a wall element comprising post members and connecting longitudinals defining recesses spaced apart, passageways in the post areas inwardly of said posts between said recesses and communicating therewith, and wainscoting grilles covering said passageways and recesses.

2. A passenger car comprising upright frame members, an outer car wall secured to said frame members, an inner wall forming with said frame members and said outer wall a plurality of recesses each adapted to receive a radiator, said inner wall being spaced inwardly from said frame members to form passageways between said members and inner wall through which supply and discharge 'pipes for said radiators may extend.

3. A passenger car comprising upright frame members, an outer wall secured to said frame members, an inner wall forming with said frame members and said cuter wall a plurality of recesses, each adapted to receive a radiator, a floor for said car, and spacer members between said upright members and said inner wall spacing said inner wall inwardly from said upright frame members and forming passages between said recesses both above and below said spacer members, through which wire conduits and supply and discharge pipes for said radiators, respectively, may extend.
